CRM Company Options "Update Partially Invoiced Orders in Sage CRM"

I have a client that is experiencing issues with the SO_SalesOrderHistoryHeader table getting updated with bad Date/User Created values when an order (originating from CRM) is partially shipped and then modified (typically line comments get added to backordered sales orders). There is an option in CRM Company Options called "Update Partially Invoiced Orders in Sage CRM" that is currently enabled, and the help shows "Select this check box if you want changes made to partially invoiced orders in Sage 100 to be updated in Sage CRM. If you select this check box, all changes to orders in the Sales Order History file that have been partially invoiced will be reflected in Sage CRM. Clear this check box if you do not want changes to partially invoiced orders in Sage 100 to be updated in Sage CRM." The CRM Specialist at Sage is not clear on what is actually updated to CRM when backordered sales orders are modified though, so before I disable this option for testing, is anyone familiar with what function this option performs? Thanks in advance!
